Selective nerve root block injection (SNRB) is an injection of long-lasting steroid (cortisone) around the nerve root as it exits the spinal column. The injection reduces the inflammation and pain caused by pressure on the nerve.
It can also be used as a diagnostic tool to help doctors determine whether the nerve is irritated by “numbing” the nerve.
How It Works
When used for treatment purposes, steroids are usually mixed with anesthetics or used alone in selective nerve root block injections. Steroids in nerve blocks work by a combination of the following mechanisms;
- Inhibits the action of certain enzymes such as phospholipase A that causes neural irritation and pain
- Block specific fibers (C Fibers) within the nerve that results in lesser pain transmitted to the brain
- Decreases the permeability of nerve fibers to receive blood, decreasing pain transmission
Neurosurgeons perform the procedure with the patient lying on the stomach on an X-ray table. The surgeon uses fluoroscopy (x-ray) to help locate the specific nerve root.
A needle is inserted into the area and the medication and an anesthetic are injected. The injection takes just several minutes. After the injection, the patient is monitored for 15-20 minutes and then released.
Most patients start noticing pain relief after the third to seventh day, which can last weeks or months.
